N. Zufferey, Scepticism in Ancient China, RThPh 2001/I, p. 1-17.
Even if there was no school of Scepticism in Ancient China, certain thinkers did express reserves about the possibility of knowledge, which can be likened to one or another of the various forms of Western Scepticism. The radical criticism of the Taoist Zhuangzi seems to be exceptional, but several Confucian philosophers and legalists (Xunzi, Han Fei, Wang Chong) clearly affirmed that knowledge cannot and should not be exercised beyond certain limits, and criticized the dominant view that reality, conceived of as a system of signs or portents, fully reveals itself to the perspicacious sage or clairvoyant.
